So I got the definitive word from Tesla that they are no longer manufacturing their NEMA 14-30 adapter for the UMC. Considering how useful this adapter is for charging from dryer sockets away from home, this is perplexing. Anyways, for those that need one, you can try your service center to see if they have any stock left, or buy a third party adapter (but you have to dial down the amps to 24 amps on the car screen before charging) from: http://www.evseadapters.com/index.php?route=product/category&path=57 OR http://www.corddepot.com/shop/ev-products/ OR make your own using instructions in: http://cosmacelf.net/Home%20Made%20Adapters.pdf Here is Tesla's response: Thank you for contacting Tesla Motors. Unfortunately, we are no longer producing the NEMA 14-30 Adapter and we have exhausted our supply for online orders. It may be possible for you to purchase an adapter directly through your local Service Center.
